Title: Production of screen plate
Inventor: TAKAGI TAMAKAZU
IPC: G03F7/12
Filed: 1988-07-08
Abstract: PURPOSE:To provide the screen plate having a sufficient thickness without narrowing the apertures thereof by forming respective plating layers of nickel chloride, copper and nickel only to bridge parts while a nonconductive synthetic resin is held packed in the apertures of a cylinder. CONSTITUTION:The nickel parts exposed by exposing and development processing are removed in an etching treatment to form the apertures D' and while the nonconductive synthetic resin 5 is held packed into the apertures D', the nickel chloride plating layer 6 and the copper plating layer 7 of prescribed thickness are successively formed on the surface of the 1st nickel plating layer 2. The 2nd nickel plating layer 8 is then formed on the surface of the plating layer 7 and the synthetic resin 5 is removed after the formation of the plating layer 8. The resulted plated roll 9 or plated plate is removed from a mother roll 1 or mother plate. The screen plate which is larger in the thickness size than heretofore by as much as the thickness component of the respective plating layers of the nickel chloride, copper and nickel is produced. in this way.

Title: Servo controller of shift mechanism
Inventor: ISHIHARA ATSUSHI
IPC: G11B21/08
Filed: 1982-09-30
Abstract: PURPOSE:To increase the distance where a servo mechanism functions effectively to a stop position with no deterioration of the stop position resolution of a shift mechanism, by moving the shift mechanism until the coincidence is obtained between a position address and a target position address and judging the shift direction in response to the position detecting signal in a stop mode. CONSTITUTION:When a linear motor 7 is once shifted toward B, the position signal given from a switching circuit 17 is reduced than the previous one. The counter of a coupling circuit 27 performs count-down by the clock signal sent from a clock signal generating circuit 29. This count output drives a driving circuit 41, and the motor 7 is moved toward A. In such a way, the shift of the motor 7 is stopped when the counter of the circuit 27 counts zero. Therefore the effective servo distance is shown by (h) in the figure at a set point (l). Thus it is possible to obtain a servo distance larger than the stop position resolution (i).

Title: Hydraulic circuit for running construction machine
Inventor: TONO MASAAKI
IPC: F15B11/16
Filed: 1988-07-08
Abstract: PURPOSE:To improve smooth high speed running and working efficiency of machines by providing a variable relief valve with a function to set relief pressure to a specific value from the signal of a speed range changeover means. CONSTITUTION:Pressure relief valves 14 and 15 are usually set at a set pressure suitable for a running motor 8 to drive a running wheel with no trouble at a low speed level, but when a pilot pressure works on receiving parts b, b through a pilot pipe route 19, ejected pressurized oil of main pumps 2 and 3 with high pressure flows in the running motor 8. Consequently, when a speed range changeover means is selected at a low speed level while working the output torque of the running motor 8 does not come to be excessive since a variable relief valves 14 and 15 are at a normal set pressure. Also when the high speed running state is set with a switch 13 closed, a changeover valve 12 comes in a position B and as a result, pressurized oil works on a receiving part b, and consequently, high pressure oil works on the running motor 8 and the machine body can run at a high speed.

IPC: H01S5/00
Filed: 1986-07-23
Abstract: PURPOSE:To increase the sensitivity of a sensor and to stabilize and reduce the sensor in size by leading both clockwise and counterclockwise laser light beams out of a laser resonator directly by an optical fiber loop. CONSTITUTION:The clockwise laser light L5 and counterclockwise laser light L6 in the laser resonator 10 are propagated in an optical fiber coupler 2e as counterclockwise laser light L7 and clockwise laser light L8 in the optical fiber loop 9. Those L7 and L8 are further guided to a photodetection fiber 3 through a coupler 2f. Then, a signal E1 corresponding to the L7 is outputted from a terminal T1 through a lock-in amplifier 5a. A signal E2 corresponding to the L8, on the other hand, passes through a lock-in amplifier 5b to become a phase signal P and a phase control signal PC at any time is generated by a phase controller 7 so as to goes to zero the signal P and sent to a modulator 8. Consequently, the resonance point in the loop 9 is stabilized. When a sensor system rotates around the loop 9, the resonance point of the L7 varies and the angle of rotation is detected.

Title: Video signal processor
Inventor: MIYAMOTO YOSHIHIRO
IPC: H04N1/405
Filed: 1979-12-28
Abstract: PURPOSE:To realize not only a binary coding of the intermediate gradation but a uniform picture quality even to the variable density of the original, by forming a pair of the adjacent picture element signals of the time-series picture element signals to compare them with the different reference level signals with every picture element and then extracting the multi-gradation binary coded signal. CONSTITUTION:In case the difference between the highest and lowest luminances of the video signal is small like the width F, the amplitude M of the reference level signal is decreased by the gain variable amplifier 15 and in accordance with the width F. Thus the binary coded signal output having an increased contrast is obtained. The contrast is increased by controlling the amplitude of the reference level signal, thus reproducing a high-contrast picture. On the other hand, the amplitude of the reference level signal is decreased in case the DC level is lowered with a small difference of luminance and a dark original surface. At the same time, the DC level sent from the variable power source 16 and to be added by the voltage adder 17 is controlled to a low level to cope with a low contrast and low luminance. Accordingly, a faithful multi-gradation binary coded signal is obtained also in this case, thus realizing a reproduction of a high-contrast gradation pattern.
